Abstract
Biliary tract carcinomas (BTC) are malignant epithelial neoplasms subdivided anatomically into: gallbladder carcinomas and carcinomas of the bile duct or cholangiocarcinomas (CCA); including intrahepatic, hilar/perihilar, and distal CCA. Adenocarcinoma accounts for the most common BTC (over 90% of all carcinomas), while other histological subtypes represent rarer forms including: poorly cohesive/signet ring cell carcinoma, which has a greater malignant potential than conventional BTC and a poorer prognosis. Only few cases have been reported in the literature to date. The positive diagnosis remains on histology. Herein, we describe a new case of poorly cohesive carcinoma of bile duct extending to the gallbladder in a 60 years old women with a fatal outcome, to raise awareness of this rare entity and to provide data for larger series.
